11:14
Do not preserve the btreeInitPage() results in PRAGMA integrity_check if there were cell sizing errors because PRAGMA cell_size_check was turned off during the btreeInitPage() call. (check-in: 743bf1f1 user: drh tags: trunk)

23:29
Correction to check-in [1025873fdf], tighten up the number of static test mutexes. (check-in: 4e515897 user: mistachkin tags: trunk)
23:12
Update clean target in MSVC makefile. (check-in: e6c03e72 user: mistachkin tags: trunk)

2015-07-02
20:12
Copy fts5.h into the build directory as part of building fts5.c. Also remove code to edit fts5parse.c from various Makefiles and add it to mkfts5c.tcl. (check-in: 4d8f03dc user: dan tags: trunk)
19:47
When doing coverage analysis of a btree page for pragma integrity_check, make the first entry (that covers the header, cell index, and gap) implied, for a performance boost and size reduction. (check-in: e53d497c user: drh tags: trunk)
18:52
Minor change to mkfts5c.tcl so that fts5.c can be used according to the instructions in loadext.html. (check-in: edbcccd3 user: dan tags: trunk)
18:47
Merge in the latest enhancements from trunks, especially the use of _byteswap_ulong() and similar intrinsics on MSVC. (check-in: 85ca4409 user: drh tags: sessions)
18:16
Add fts5_source_id() SQL function, similar to sqlite_source_id(). (check-in: ec257348 user: dan tags: trunk)
16:52
Fix harmless compiler warnings and one macro VVA_ONLY macro usage issue. (check-in: bcc8a755 user: mistachkin tags: trunk)
16:50
Simplify FTS5 handling in the MSVC makefile. (check-in: f022e043 user: mistachkin tags: trunk)
16:29
Fix a (harmless) shadowed local variable definition in the integrity_check logic. (check-in: 3a26a919 user: drh tags: trunk)
16:17
Smaller and faster PRAGMA integrity_check that also does a better job of detecting errors. Some output text describing discovered file corruption has changed for clarity. (check-in: 251a7590 user: drh tags: trunk)
15:52
Remove "#ifdef SQLITE_ENABLE_FTS5" from individual fts5 source files. Add a single "#if !defined(SQLITE_CORE) || defined(SQLITE_ENABLE_FTS5)" to fts5.c. (check-in: 7819002e user: dan tags: trunk)
01:38
Add the --shrink-memory option to the speedtest1 test program. (check-in: c9ddbd88 user: drh tags: trunk)
2015-07-01
19:59
Avoid create a stack from in sqlite3BackupUpdate() in the common case where the first argument is NULL. (check-in: 2a897b9e user: drh tags: trunk)
17:53
Simplification of PRAGMA integrity_check logic. Make sure that the depth of the right-most subtree is correct. Size reduction and performance increase, with no change in output. (check-in: 550705fc user: drh tags: trunk)
17:13
Rework the PRAGMA integrity_check logic. Simplify the checkTreePage() routine and clean up the error messages generated. (Closed-Leaf check-in: 1c522123 user: drh tags: integrity-check-refactor)
04:08
Fix some harmless compiler warnings. (check-in: 307195c8 user: drh tags: trunk)
01:31
Change integrity_check to analyze the cells of a page in reverse order, as this will tend to insert the cells into the analysis heap in increasing order by address, which is the most efficient way to load a min-heap. (check-in: 59ad912c user: drh tags: trunk)
2015-06-30
17:28
Make use of the _byteswap_ushort() and _byteswap_ulong() compiler intrinsics for MSVC, when available. (check-in: fe144dd7 user: mistachkin tags: trunk)
16:29
Merge all the latest enhancements from trunk. This merge include FTS5 and a number of notable performance enhancements. (check-in: 39936b33 user: drh tags: sessions)
15:10
Make use of built-in bswap32() and bswap16() functions in GCC/Clang for a significant performance improvement there. (check-in: 8bfcda3d user: drh tags: trunk)
14:01
Only use __builtin_bswap16() with GCC 4.8 and later. (Closed-Leaf check-in: ce8177e3 user: drh tags: bswap-functions)
13:28
Remove the use of htonl() in the previous check-in due to linkage issues. Add the get2byteAligned() macro and use it for access to the cell offsets on btree pages for about a 1% performance gain. (check-in: 79ff36b7 user: drh tags: bswap-functions)
12:47
Make use of htonl() and __builtin_bswap32() for faster implementations of sqlite3Get4byte() and sqlite3Put4byte(). (check-in: bc27ebd7 user: drh tags: bswap-functions)
11:07
Change an unreachable branch into an assert() in sqlite3PagerAcquire() and optimize sqlite3PcacheOpenSavepoint() by factoring out rarely used code into a subroutine. (check-in: b406b20e user: drh tags: trunk)
03:57
Optimization to the sqlite3PcacheFetch() logic. (check-in: d9a0481c user: drh tags: trunk)
03:34
Put all variable declarations for sqlite3PagerWrite() at the beginning of the block. Syntax only - no logic changes. (check-in: a0fa6b3b user: drh tags: trunk)
03:18
Implement sqlite3Strlen30() using strlen() from the C library. (check-in: 8001aa52 user: drh tags: trunk)
03:13
Change sqlite3ApiExit() so that its first argument is never NULL. (check-in: 791b706e user: drh tags: trunk)
